Average = 0.56 inches
Solution:
Given data: Total rainfall = 16.8 inches
Total number of days for a month = 30
To find the average of the rainfall.
Formula for average:
= 0.56 inches
Average = 0.56 inches
Hence, average of daily rainfall is 0.56 inches.
Circumference: 2πr
Circumference: 2(3.14)(x + 1)
Circumference: 6.28(x + 1)
Circumference: 6.28(x) + 6.28(1)
Circumference: 6.28x + 6.28
Area: πr²
Area: 3.14(x + 1)²
Area: 3.14(x +1)(x + 1)
Area: 3.14(x(x + 1) + 1(x + 1))
Area: 3.14(x(x) + x(1) + 1(x) 1(1))
Area: 3.14(x² + x + x + 1)
Area: 3.14(x² + 2x + 1)
Area: 3.14(x²) + 3.14(2x) + 3.14(1)
Area: 3.14x² + 6.28x + 3.14
Answer:
3, 6, 9
Step-by-step explanation:
When changing a fraction to a decimal, you divide the numerator by the denominator. For EX.
1/3= 1 divided by 3
1 divided by 3 is 0.3333333333333
1/6
1 divided by 6 is 1.6666666666666
1/9
1 divided by 9 is 0.1111111111111111111111
